Very well expainted smps thanks upload more videos

you are the best i enjoy learning electronic from you. ❤ from Aus.

Informative video. Thank u so much.

Nice lods and thanks for sharing your knowledge ❤

ماشاء اللہ بھائی

Great and most sweetest lesson I ever enjoy in electronics. Am currently having an issue working on a hybrid high frequency inverter showing error 09,after changing output mosfets,it change to 06,then I observe some zener diodes I changed off hand maybe I didn't get the real voltages,pls can u help me with real values of those zener diodes on the small output transformer...with codes zd3,7,8 . It's 5kva/48v. Thanks and more blessings to your home

Very informative....thanks sir ji...

Excellent explanation

ممنون مهندس عالی بود

Very nice sir

Very good and useful information sir thanks for sharing this knowledge to us

It's simple good explanation guruji

Nice video sir

Excellent explanation _ GOOD JOB.

Very nice good

Jazak Allah Khair.

Thank you my brother for sharing all this great knowledge really appreciate your work I have a smps that used to work from 100v to 240v AC but recently started working only at 240v can you please tell me what might be the problem why it's not working at 110v anymore thanks in advance.

Great teacher. Ap pr ALLAH ki rehmatain hon

amazing analysis

Excellent sir, Thank you so much. Thank god for being a student of you sir🙏 Greeting from chennai. india

@HaseebElectronics It's worth to also mention that it may be also a failure in the transformer winding... I'm fixing right now a Modecom ATX SMPS with both failed switching transistors,bruned fuse and desoldered one leg of subber resdistor. I fixed that problems, turned on PSU, and I notice that output voltages are very low, fo example 12V rails has 1 point sth Volt. I also noticed that snubber resitor gets very hot and after some period of time, transystors failed once again and "blew" a fuse once again... After that failure, I inspected PSU closer and more precisely and I noticed that transfomer has sheinked nad wavy isolation. and looking from the top I also noticed that isolation layersare melted, so I removed transformer, disassembled it, what wasn't easy, because isolation tape was so badly overheated that it falls apart, so I had to scrape it peace by peace and I noticed that one of the wires in the center-tap tail is blackend partially, burned!!!! I have 2nd PSU based on the same chassis, but with increased output power, so I borowed transformer and transistors from it, put my patient back together and bam, it worked!!!! Transformer failed, but I have to admit that anyways it done the job perfectly, becuse isolution worked and didn't allow the sec. winding short itself with primary!!

you are always clear explanation of smps circuit

You are great sir

Beautiful lecture, nicely explained tks A LOT

Zbardast sharing

Mashallah Nice Sharing🌹💞💕👌 Stay Connected 👍

Super video 👍

May God reward you, brother Haseeb

Thank you very much sir 🙏🙏🙏

Well done Haseeb thanks and greetings from Sydney.

Nice explaination. Basicly use off line transformer. DC swich only produce one direction magnetic field.

Shukriya Maestro

Great... Thanks for sharing

Excellent information. Thank you sir.

Great Teacher l❤

Very good explain sir Iam from srilanka

Sir you're videos are extremely helpful and I would like to thank you for that, can you make a video about :how to convert 3 phase input of VFD into Sigle phase input but the output of both are 3 phase. we only want to change the input while the output remains the same

Good sharing

Thank you very much for this video. Please explain the output section of a high frequency inverter. That is from 300 volts dc to 220 volts ac 50 Hz. Iam getting low output voltage. Fans are running slowly. How can I increase output voltage. Please explain. 🙏

Very nice 👍👍👌👌👍

Sir very well explained thanks for sharing💯❤

Good video

nice sir. 5 star.

Good evening brother. I hope our whole family is doing well. Great sharing as always

Nice info ones again ?Can a optocoupler use for the switching????

Very informative video sir. You said in absence of snubber, it will cause oscillation effect. I would like to learn more on this. If you have any example video of some snubber circuit failed and cause the oscillation effect would be very helpful for me. Thank you sir.

Thank you so much..

W assalam Bhai Mashallah zaberdest Bhai nice video

good video

Jzk Allah kheir

Nice video

thx yours video and sharing

Thank You Very much Sir! I realy apreciate your effort. It is always helpful.

Merci beaucoup

Thank you!

Always love your videos... please post more repair videos... 5hank you!

Please do video of RC Shubert circuit, differnce between rc and rcd snubbed. Thank you

Thanks Sir.

Big like For Good Work My Brother

Well explain 👍 thank you so much for sharing this video stay connected

This man his the best

i think that the resistance in snubbing circuit is much more greater that the resistance of the main winding. so even if the diode in the snubbing circuit is failed, there will be still switching. correct me if i am wrong.

Thanks!

helo sir,, may i ask u about my 330amp welding machine proquip brand the welding output is very low it only spark 4or5times then d overheat light will switch on then the smps resistor and switching transistor are very heat.

Excellent work brother 👍

many thanks, sir.

Tnx👏👏👏👏👏

Hello sir thanks a lot for your good explanation. I have a question: in a smps that I want to repair it, with replace x capacitor voltage on secondary side appear on 12V. But when install a load to it voltage dropped and fluctuated to 0-5 volt and load does not work. Please help me. 🙏🏻🙏🏻🙏🏻⚘

I have a 36V/10A SMPS which keeps burning one of the two power transistors a few seconds after the load is connected. It is always the same transistor. Could you explain that for me? Thank you

Hi, my 120W smps output voltage good but output current very low, i am unable to use 12v 5A load, i checked all components good even low current, so what component to be replace in smps ?

Sir hasseb how are you ?? I have an SMPS of a sattelite receiver with IC number SD6835 have external sensor resistor 2 OHM connected in pin CS number 2 but now the resistance show 0.7ohm in multimeter When i connect the SMPS in the motherboard of the receiver no power on and the vcc capacitor and the main capiacitor are varying when i disconnect the smps from the motherboard i get the 5 volt . when i reconnected to the motherboard again no power on and capacitor baby and main are varying can you help me to r this issue ??? May i have to change the 2 external sense resistor SMD connected in parrallele ??? Number of resistor SMD 2R0 SUUPORT PLEASE

Simply excellent!!!

Wa alikuma salam wa rahmatullah wa barakatuhw

Low side switching is simple and easy to protect its gate but high side switching is something else I use gate drivers transformer and switching 22 volt to mosfets gate the gate is rated 20vgs but I measure the gate voltage and it’s 160 volt volt from the two switch forward converter can you explain why the mosfet gat no blowing out at the voltage I don’t have a ziner diodes to protect the gate

Pls can you do a video of how to solve oscillating problem in igbt welding machine

I AM REGULARLY VIEW YOUR CHANNEL VIDEOS, VERY VERY INFORMATIVE I WOULD LIKE TO KNOW ABOUT CAN WE INJECT VCC VOLTAGE FROM EXTERNAL SOURCES IS IT FEASIBLE AND POSSIBLE PLEASE ANSWER OR MAKE A VIDEO
